Elton John had crowds in tears during an emotional tribute to George Michael

Sir Elton John treated a tearful crowd to an emotional performance on Wednesday (Dec. 28) in Las Vegas, where he paid tribute to his long-time freind George Michael during a concert in Las Vegas on Wednesday.

The star sung a rendition of "Don't Let the Sun Go Down on Me ," a duet he had previously performed with the late singer who passed away on Christmas Day. Following the performance, Elton looked visibly upset and turned his back to the audience to compose himself. A fan at the show told the Daily Mail: "Elton had sung a song in memory of John Lennon when he spoke about George Michael. After he sang for George, he turned his back on the audience and was shaking and looked like he was crying. I was in tears and so was everyone around me. There were thousands of us in tears and it was very emotional. He received a standing ovation and had to be consoled by a band member before beginning the rest of the show. There wasn't a dry eye in the house."

While it is thought that the 69-year-old will be singing at George's funeral, which will take place at Highgate cemetery in London, it has also been reported that many friends and colleagues of the former Wham! band member are already in the early stages of planning to put on a charity concert in tribute to him, with names including Aretha Franklin and George's friend and Wham! bandmate Andrew Ridgeley interested in participating.
